When I was younger airlines had tags on the seats where it indicated if you wanted to be woken for food. But that's now not the case. You could inform the flight attendant when you board that you want to be woken for food, but there is the chance that he/she might forget and/or that flight attendant won't be serving in your cabin. Your best bet probably would be to ask your neighbor to wake you when food comes. You could even write a sticky note and post it on the back of the seat in front of you to remind them.
